20 GHA l Switchgear extension and replacement of a panel
Replacement of a panel within a 4
switchgear system
Safety provisions4.1
Warning!
Comply with the safety provisions on page 6 and 8.
Warning!
Confusing the busbar system involves a risk of injury. The term
Busbar 1 (BB1) refers to the busbar arranged in the rear area of the
panel, and the term Busbar 2 (BB2) to the busbar arranged in the up-
per part of the panel.
During replacement, busbar 1 and busbar 2 must be identified
clearly on the adjacent panels.
Earthed as well as energized busbars must be identified by the ap-
propriate warning and information signs.
Warning!
Risk of injuries. The mounted black end caps on the busbar ends
and the silicone sleeves of the busbar link are surge-proof and must
not be subjected to any mechanical stress.
Warning!
The initial position as shown, and the workflow described are in-
tended as examples only.
Before assembly is started, a complete description of the complete
workflow of a switchgear replacement must be prepared and com-
plied with in accordance with the local circumstances and condi-
tions.
Important information4.2
The surge-proof black end caps and the silicone sleeves of the busbar
links are safe to touch due to an earthed external conductive surface.
Before positioning new panels, insert the busbar clamping contacts into
the busbar tubes of the left-hand panel concerned. Inserting the clamping
contacts after screw-fastening the panels would be very time-consuming.
The silicone link sleeves connecting the existing switchgear to the exten-
sion panel may only be mounted on site.
